2.5 WALL SLEEVE INSTALLATION
Wall Case Installation Data
General
Generally, units are installed 3" to 5" above the floor
(flush to finished floor installation is possible) as near to
the center of the room as possible; underneath a win-
dow or a glass panel is typical. Normal installation of
the wall case allows installation flexibility; from flush
with the finished interior wall to a minimum of 1/4" of the
wall case extending beyond the finished exterior of the
building.
Special consideration must be given to installations
where the wall case does not extend a minimum of 1/4"
beyond the finished exterior wall.
Regardless of the installation, there are several things
to consider when selecting a location for installing the
unit. For instance, drapery location could interfere with
air discharge, and placement of furniture may have an
impact on the performance of the unit. The following
information is intended to minimize installation prob-
lems and assure you of a trouble-free installation.
Refer to last page for required wall opening dimen-
sions. Minimum recommended interior and exterior
case projection for standard wall thicknesses are
shown in the drawings in this manual. The case may be
installed flush with the finished indoor wall.
Mounting an outdoor grille or louver section to the build-
ing face may cause a space between the outdoor coil
and the louver section. Air splitters, aligned with the
ends of the outdoor coil, must be installed between the
outdoor coil inlet and outlet air streams. Gaps between
the outdoor coil and the louver section may allow con-
denser air recirculation and affect the operation of the
unit.
For new construction, early planning with the architect
is necessary. Unit location, electrical connection
locations, and wall openings of proper dimension are
essential to avoid the necessity of rework, fillers,
framing, moving electrical outlets, and other expensive
modifications.
For existing construction it is important that carpentry,
masonry and electrical work be performed by compe-
tent, qualified personnel.
Since installations in exist-
ing construction may involve removal of building
material from the structure, location of the wall
case must be precisely done.
The wall case should be level from side to side
and from level to 1/4 bubble tilt to the outdoors.
The condensate disposal system in the unit is
designed to dissipate the condensate water gen-
erated during cooling operation in accordance
with ARI standards and actually uses this water
for maximum unit efficiency. A level unit will also
insure proper performance of the Internal
Condensate Removal (ICR) system optional on
heat pump units.
